Petraeus resigned November 9 after revealing that he 'd been involved in an extramarital affair .

U.S. officials said the FBI discovered Petraeus was involved with Broadwell , a woman who was under investigation for sending allegedly harassing and anonymous e-mails to Jill Kelley , a Tampa socialite who was friendly with Petraeus and his wife .

Sources close to Kelley said she had not been romantically involved with Petraeus .

During the investigation the FBI obtained Broadwell 's computer and discovered she had classified materials . Investigators also searched Broadwell 's home in North Carolina . Sources said the materials were technically classified but not highly sensitive . Still the FBI and Justice Department prosecutors have not resolved whether Broadwell will face charges for having such materials in her personal possession .

Sources close to Broadwell acknowledged that issue has not been resolved .

Broadwell , 40 , wrote a biography of Petraeus , a retired general who led U.S. forces in Iraq and later in Afghanistan . A former Army reservist , Broadwell 's security clearance was suspended after details surfaced about her possessing classified materials .

During the investigation it also came to light that Kelley and Army Gen. John Allen were exchanging e-mails , some of which might have been considered inappropriate . That matter was turned over to the Pentagon 's inspector general for investigation .
